Senior AI Software Engineer | .NET & Azure | £70,000 - £100,000

Are you a strong C#/.NET and Azure engineer who has recently started building AI agents or applications using LLMs?

I'm working on an exciting opportunity with a major technology consultancy, supporting a public-sector client in Cardiff.

They're looking for an experienced software engineer who can combine solid development skills with practical, demonstrable AI experience.

You don't need to be an AI research expert. If you've been tasked with building agents or LLM-powered applications in your current role and can talk confidently about what you've built, this could be a great next step.

Key experience:

• Strong C#/.NET and Microsoft Azure
• Hands-on experience building LLM applications or AI agents
• Exposure to Azure OpenAI, RAG, APIs or agent orchestration
• Ability to explain and demonstrate your technical work

Location: Cardiff

Working pattern: Primarily remote, with around 2-3 days per month in Cardiff

Salary: £70,000-£100,000, depending on experience

SC clearance eligibility required

Interview: One technical Teams interview
